First Great Eastern was a train operating company (TOC) that operated suburban, local and medium distance train services from London Liverpool Street via Romford to Essex and Ipswich in the United Kingdom on the Great Eastern Main Line (GEML) railway.

First Group gained the Great Eastern franchise in 1997 as part of the Privatisation of British Rail. In 2003, as part of a franchise reorganisation planned by the then Strategic Rail Authority, the Great Eastern was to be merged to form a 'Greater Anglia' franchise. This new contract was won by National Express Group who took over First Great Eastern operations on April 1, 2004 using the brand name 'one', which has since been rebranded as National Express East Anglia.

Most lines previously served by First Great Eastern are electrified with 25 kV AC overhead catenary wires, with the exception of the Marks Tey to Sudbury branch line, which is served by diesel units.

A diesel multiple unit (DMU), most likely a Class 153 Sprinter, was used on the Sudbury-Marks Tey branch line due to the lack of electrification.
